"Standard software doesn't satisfy all our needs"
Standard software tends to reach as many customers as possible. And often it doesn't contain any narrowly focused industry functions. The more unique needs your company has, the more restrictions you will have on standard software and the need for additional payments.
A specific set of tables, databases, reports, documents, and invoices - all of this functionality can be contained in one place by your custom software.
This will speed up your work and allow you to focus on the development and expansion of the business.
